Abstract

A method of encapsulating spring units is disclosed. The method comprises inserting an uncompressed spring unit into an insertion device, moving the insertion device between a pair of webs, tightening or tensioning the webs around the insertion device, compressing the spring unit, tightening the webs around the compressed spring unit, withdrawing the insertion device as the webs are tightened, and, while the spring unit is compressed, connecting the webs together.

Description

1 SPRING UNIT ASSEMBLY This invention relates to apparatus for and a method of assembling and encapsulating spring units for use in mattresses or other upholstery units.
The term "spring unit" used herein means a plurality of spring coils arranged spatially in file and joined together by wire. The spring coils and joining wire may be formed separately and joined by a length or lengths or wire.
The term "web" used herein is to be construed as meaning cloth, fabric, laminated material or any other material used in, or capable of being used in, the S production of mattresses and other upholstery units.
It is an aim of the present invention to provide an effective and economically viable apparatus for and method of providing assemblies of spring units for use in mattresses or other upholstery units.
SAccording to one aspect of the present invention :6i: there is provided apparatus for encapsulating spring units as hereinbefore defined between a pair of webs as hereinbefore defined, the apparatus comprising an insertion device for inserting a one of the spring units between the pair of webs, means for tightening or tensioning the webs about the spring unit, compression means for compressing the spring unit, and securing means for securing the webs together in close proximity to the compressed spring unit to encapsulate same.
Preferably the securing means is a long arm sewing machine. Alternatively it could be a heat sealer depending upon the constitution of the webs.
The spring unit insertion device is preferably in channel or trough-shaped member which is withdrawable before, or as, the webs are tightened around the spring unit.
Preferably the web tensioning means comprises, at one side of the long arm sewing machine, a direction-reversible roller unit between which the webs are fed and, at the other side of the long arm sewing machine, a reciprocable puller bar.
Any other convenient tensioning arrangement can be employed.
Preferably the spring unit compression means is a pair of oppositely-movable pressing plates controlled by pneumatic rams.
Also according to another aspect of the present invention there is provided a method of encapsulating spring units between a pair of webs, the method comprising inserting a one of the spring units between a pair of webs connected together along a line parallel with the spring unit, tensioning the webs around the ':spring unit, compressing the spring unit, and, while compressed, connecting the webs together in close proximity to the ccmpressed spring unit at the other side of the spring unit from the first mentioned line of connection.
An embodiment of the present invention will now be described, by way of example, with reference to the accompanying diagrammatic drawings in which:- WO 91/05732 PCT/GB90/01602 3 Figure 1 is a side view of a long arm sewing machine used in the apparatus of the present invention; Figure 2 is an end view of the sewing machine; Figure 3 is a general view of the layout of the apparatus according to the present invention and illustrating a first method step; and Figures 4 to 6 respectively illustrate the second, third and final actions of the apparatus.
The spring unit assembling and encapsulating apparatus comprises a long arm sewing machine movable to-and-fro along a track 11, a web conveying and tensioning system 12, a spring unit insertion device 13, and a spring unit compression device 14.
The general layout of the apparatus is most clearly seen in Figure 3.
The long arm sewing machine 10 comprises parallel arms 15 between which pzarallel lengths of web 16 can pass the sewing machine 17 being carried laterally of the arms The sewing machine needle and bedplate are respectively indicated at 18 and 19 respectively.
The long arm sewing machine 10 is movable to-and-fro along the track 11 by an endless chain driven by a reversible motor 21 and gear transmission 22, the sewing machine 10 being coupled to the endless chain 20 by a mechanical coupler 23 of any WO 91/05732 PCT/GB90/01602 4 convenient form and being provided with wheels 24 for running along the track 11.
The effective stitching line of the long arm sewing machine 10 is indicated at The web conveying an. tensioning system 12 comprises, at one side of the long arm sewing machine 10, a pair of direction-reersibie driven puller rollers 26, and, at the other side, a puller bar 27 releasably mounted on a carriage 28 which is movable to-and-fro as indicated at 29 across a pull-off table 30 by a motor 31 and suitable transmission (not shown).
The spring unit insertion device 13 is a channel or trough-shaped member 32 insertible manually or by power means, for example a ram, between the lengths of web 16. The channel or trough-shaped member 32 is thus reciprocable to-anc'-fro in the direction of arrow 33.
The spring unit compression device 14 comprises a pair of double-acting pneumatic rams 34, whereof the piston rods are indicated at 35 and pressure plates at 36. The latter have lateral plates 37 which ensure that only one spring unit 30-40 at a time is within the compression device 14.
The use of a long arm sewing machine 10 permits lines of stitching to be effected very close to the spring unit compression device 14, for example as close to 20mm. or thereabouts.
In use, two webs 16 are fed between the roller 26, are stitched together at 41/, and the puller bar 27 is WO 91/05732 PCT/GB90/01602 inserted therebetween and is then miounted on the carriage 28.
A first spring unit 38 is disposed in the channel or trough member 32 and inserted between the webs 16 at the compression unit 14 (Figure the rollers 26 being operated to tension the webs 16 around the spring unit 38, the channel or trough member 32 then being withdrawn, the compression unit 14 operated to compress the spring unit 38 and the long arm sewing machine operated to stitch the webs 16 together closely adjacent the compressed spring unit 38 to encapsulate same (Figure The compression unit 14 is then opened and the rollers 26 and the carriage 28 to move the encapsulated sprilng unit 38 away from the sewing machiine 17 (Figure 6).
A second spring unit 39 is then slid as aforesaid between the webs 16, is compressed, and is encapsulated by stitching as aforesaid, the rollers 26 pulling the webs 16 to tighten same around the second spring unit 39 prior to compression and encapsulation.
This action is repeated until all spring units are encapsulated.
The end product is a series of parallel spring units 38-40 individually encapsulated under compression between the webs 16.
The ends of the webs 16 at right angles to the spring units 38-40 are closed by stitching for example, and the encapsulated spring unit assembly can then be.
encased to form a mattress or other upholstery unit.
